When pilots say “pan” over the radio, it is an aviation communication term used to indicate an urgent situation. The term “pan” is derived from the French word “panne,” which means “breakdown” or “failure.” It is used to grab the attention of air traffic controllers and other pilots to indicate that the aircraft or crew is experiencing an emergency or a situation that requires immediate attention but is not as severe as a “mayday” distress call.

The use of “pan” is part of the International Civil Aviation Organization (ICAO) standard radiotelephony phraseology, which helps ensure clear and concise communication during emergencies. By using “pan,” pilots can communicate their urgent need for assistance and prompt attention while distinguishing it from the more serious distress call of “mayday.”

Examples of situations that may warrant a “pan” call include an engine malfunction, a system failure, a medical emergency, or any other critical situation that requires immediate attention or assistance but does not pose an immediate threat to the safety of the aircraft or occupants.

Upon hearing a “pan” call, air traffic controllers will respond promptly and provide necessary support, such as providing priority handling, clearance for emergency landing, routing assistance, or coordinating with emergency services if required.

It’s important to note that “pan” calls should only be used when there is a genuine urgency or emergency situation that requires immediate attention. Pilots are trained to make the appropriate judgment when deciding to make a “pan” call based on the severity of the situation and the potential impact on the safety of the flight.
